Good question... gpib(4) binds to cec(4), but its man page does not look
too encouraging.

You configure it into the kernel. It might be modularized, but I wouldn't know.

In the end, you'd need a userland library that interfaces with the kernel
to communicate via gpib, and is itself used by applications. ISTR that
there used to be a linux oriented project for control and measuring
applications via gpib - it may be reusable via a shim layer.

As it is, though, what gpib support NetBSD has seems mostly targeted
towards hp-ib  devices. I don't know how far away it is from exchanging
strings with devices on the gpi-bus.
